Everything You Need to Know About Outlander Season 4: The Release Date, New Cast, and More

New Additions to the Cast

Outlander has already filled a few key roles for season four. Now that Maria Doyle Kennedy's lengthy run as Siobhan Sadler on Orphan Black is at an end, we're excited to see the Irish actress joining Outlander as Aunt Jocasta. The strong-willed and opinionated character is the youngest sister of Ellen, Colum, and Dougal MacKenzie, and grew up with the family at Castle Leoch. Later on in life, she fled with her husband to an American colony in North Carolina, where she bought a large plantation with smuggled gold. Jocasta plays a big role in Claire and Jamie's eventual arrival in the colonies, since she offers them a place at her plantation, River Run.

Ed Speleers, a Downton Abbey and Wolf Hall alum, is playing Stephen Bonnet. Without giving too much away, the villainous Irish pirate and smuggler's story will intersect with Brianna's fate in a horrific way. Fingers crossed the writers decide to switch up their interaction for TV.
